Abstract

Un organe d'usure ameliore (15) est utile pour proteger la partie du bord du fond (14) de la paroi laterale (11, 12) d'un organe de terrassement (10). Des goujons amovibles (33) passent au travers d'une anse de fond en forme de U (25) de l'organe d'usure (15) et la partie de bordure de fond (14) de l'organe lateral (11, 12). Les goujons (33) peuvent etre verrouilles pour empecher leur deplacement axial, par des bagues de verrouillage (35) logees dans des evidements opposes interieurement (34) des jambes (26, 29) de l'anse (25). Un organe d'usure lourd ayant la forme d'une demi-fleche (16) peut etre fixe sur le bord avant de l'organe de paroi laterale (11, 12) au-dessus de l'anse en forme de U (25). Cette conception presente les avantages d'etre simple, economique et permet le changement rapide de l'organe d'usure (15).
